Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display device. Background Art

[0002] With the development of the display industry, narrow frame design has become an important research direction. Narrow frame display devices bring users stunning visual effects and excellent visual experience. However, the narrow module frame limits the fixation and protection of the display panel, making it more prone to edge breakage and panel shedding, and the material and process processing costs are relatively high.

[0003] In the existing narrow-frame technology, large-size display devices generally use side sealing and other methods for the glass sides to increase the buffer protection of the glass sides and reduce glass microcracks, etc., to reduce the risk of display panel screen fragmentation. At the same time, the side frames are cancelled and a wider bottom frame is reserved to prevent glass impact. When the side frames are cancelled, the bottom frame is still large, and the sides and top of the glass are almost exposed, and the bottom frame has no obvious protective effect on them. Therefore, how to provide a display device that can effectively protect the display panel and achieve the visual effect of a narrow frame has become a technical problem that needs to be solved.

[0041] The present application provides a display device 1000 that can effectively protect the display panel and achieve a visual effect of a narrow frame. The display device 1000 includes but is not limited to a liquid crystal display (LCD), an organic electroluminescence display (OLED), or a micro-light emitting diode display (Micro-LED).

[0042] See also Figure 1 The display device 1000 at least includes a display panel 100 , a backlight module 200 , a side frame 300 and an adhesive member 400 .

[0043] Optional, see Figure 2 The display panel 100 includes a color filter substrate 110, a TFT array substrate 120, and a liquid crystal layer 130. After the color filter substrate 110 and the TFT array substrate 120 are assembled, the periphery of the color filter substrate 110 and the TFT array substrate 120 are sealed by a glue layer. Liquid crystal molecules are sealed in the gap between the color filter substrate 110 and the TFT array substrate 120 to form a liquid crystal layer 130.

[0044] See also Figure 1 The display panel 100 includes a top surface 101 and a bottom surface 102 disposed opposite to each other, and a side surface connected between the top surface 101 and the bottom surface 102. Optionally, the color filter substrate 110 is located on the upper side of the TFT array substrate 120.

[0045] The top surface 101 of the display panel 100 is the surface of the color filter substrate 110 that is away from the TFT array substrate 120. The top surface 101 of the display panel 100 is the surface of the TFT array substrate 120 that is away from the color filter substrate 110.

[0046] The backlight module 200 and the display panel 100 are fixedly connected to the bottom surface 102 of the display panel 100 , and the backlight module 200 and the display panel 100 are fixed into a whole in the thickness direction.

[0047] See also Figure 1 The side frame 300 includes a front plate 310, a side plate 320 and a rear plate 330 connected in sequence. The cross section of the side frame 300 is substantially C-shaped.

[0048] See also Figure 1 The front plate 310 is attached to the top surface 101 of the display panel 100 .

[0049] Optional, see Figure 1 The display panel 100 includes but is not limited to a first protective film 140, a color filter substrate 110, a TFT array substrate 120, and a second protective film 150 which are sequentially arranged. The first protective film 140 can also be an upper polarizer. The second protective film 150 can also be a lower polarizer or a lower protective foam.

[0050] See also Figure 1 The first protective film 140 is designed to be inwardly shrunk at the narrow frame compared to the color filter substrate 110, and the inwardly shrunk width is ≥1mm, so as to expose the bonding area on the side of the color filter substrate 110 away from the TFT array substrate 120, so as to facilitate the front plate 310 to be bonded to the bonding area at the top surface 101 of the display panel 100. Among them, the bonding area of ​​the front plate 310 and the display panel 100 is surface-to-surface bonding, and the surface-to-surface bonding width is ≥1mm, so the front plate 310 of the side frame 300 and the display panel 100 are assembled with good stability.

[0051] See also Figure 1 , the side plate 320 is opposite to the side surface of the display panel 100 .

[0052] Specifically, one side of the backlight module 200 is flush or approximately flush with one side of the display panel 100. The side plate 320 is opposite to the side of the backlight module 200 and the side of the display panel 100 with a small gap therebetween.

[0053] See also Figure 1 The rear plate 330 is fixedly connected to the side of the backlight module 200 away from the display panel 100. The rear plate 330 is arranged on the side of the backlight module 200 away from the display panel 100, and the fixing method between the rear plate 330 and the backlight module 200 includes but is not limited to a snap connection, a crimping connection, a screw connection, etc.

[0054] See also Figure 1 The adhesive member 400 is disposed in the gap between the side frame 300 and the side of the backlight module 200 and the side of the display panel 100. The adhesive member 400 is bonded between the side plate 320 and the side of the display panel 100. The side frame 300 is fixed to the backlight module 200 and the display panel 100 as a whole through the adhesive member 400.

[0055] For details, please refer to Figure 1 , one side of the adhesive 400 is bonded to the side plate 320, and the other end of the adhesive 400 is bonded to the side of the backlight module 200 and the side of the display panel 100. In this way, there is no gap between the side frame 300 and the adhesive 400, and there is no gap between the adhesive 400 and the sides of the display panel 100 and the backlight module 200. Therefore, there is no gap between the side frame 300 and the sides of the display panel 100 and the backlight module 200, so that the narrow frame design of the display device 1000 is realized. The narrow frame width described in this application refers to the distance between the display area boundary of the display panel 100 and the outer side of the side frame 300.

[0056] During assembly, the display panel 100 is first fixed along the thickness direction, and the side frame 300 is pressed and fixed to at least one of the top, left and right sides of the display panel 100 and the backlight module 200 through the adhesive 400 to fix the display panel 100, the backlight module 200 and the side frame 300 together.

[0057] Compared with the general technology, the display panel 100 has no side frame 300 and the side of the display panel 100 is sealed with glue, and the glass side of the display panel 100 is partially exposed, which has the risk of being damaged by collision and has weak impact resistance.

[0058] The display device 1000 provided in the present application is designed such that the display panel 100 includes a top surface 101 and a bottom surface 102 arranged back to back, and a side surface connected between the top surface 101 and the bottom surface 102; the backlight module 200 and the display panel 100 are fixedly connected to the bottom surface 102 of the display panel 100; the side frame 300 includes a front plate 310, a side plate 320 and a rear plate 330 connected in sequence, the front plate 310 is attached to the top surface 101 of the display panel 100, the side plate 320 is opposite to the side of the display panel 100, and the rear plate 330 is fixedly connected to the side of the backlight module 200 away from the display panel 100; the adhesive 400 is bonded between the side plate 320 and the side of the display panel 100. A side frame 300 is set on the side of the display panel 100 and the backlight module 200 and fixed to the side of the display panel 100 and the backlight module 200 to protect the glass side of the display panel 100. At the same time, an adhesive 400 is bonded between the side plate 320 of the side frame 300 and the side of the display panel 100 to achieve gapless assembly between the side frame 300 and the display panel 100. While reducing the border width of the display device 1000, the product side has a better protection effect, and the material cost is low and the assembly process is simple.

[0059] Optional, see Figure 1 , the adhesive 400 is a compressible adhesive. The adhesive 400 is in a compressed state between the side plate 320 and the side of the display panel 100. For example, the thickness of the adhesive 400 in an uncompressed state is h1, and one side of the adhesive 400 is bonded to the side plate 320. When the side frame 300 is installed on the display panel 100 and the backlight module 200, the other side of the adhesive 400 is bonded to the side of the display panel 100 and / or the backlight module 200. The side frame 300 compresses the adhesive 400 during the installation process, so that the thickness of the adhesive 400 is h2, and h2 is less than h1. For example, h1 is 4 mm and h2 is 1 mm.

[0060] By setting the adhesive 400 as a compressible adhesive, and the adhesive 400 is in a compressed state between the side panel 320 and the side of the display panel 100, the side frame 300 compresses the adhesive 400 during the installation process, which not only allows the two sides of the adhesive 400 to be respectively adhered between the side panel 320 and the side of the display panel 100 to achieve gapless assembly, but also allows the thickness of the adhesive 400 to be compressed to an extremely small value, thereby reducing the gap between the side panel 320 and the side of the display panel 100, and further reducing the frame width.

[0061] For example, the adhesive member 400 is double-sided foam adhesive, double-sided tape, paste sealant, rubber tape, silicone tape, etc.

[0062] See also Figure 3, the adhesive component 400 is foam adhesive 410 .

[0063] Optionally, the side frame 300 includes but is not limited to an injection-molded plastic frame, a metal frame, etc. The side frame 300 has a certain degree of ductility, so that the side frame 300 is deformed to a certain extent during the assembly process. The distance between the front plate 310 and the rear plate 330 of the side frame 300 increases under the action of external force, and the display panel 100 and the backlight module 200 are arranged in the space between the front plate 310 and the rear plate 330. The side plate 320 is pushed toward the side where the display panel 100 is located, so that the adhesive 400 on the side plate 320 is adhered to the side of the display panel 100 and compressed to a smaller thickness. At this time, the side frame 300 is located in a suitable position. After the external force is removed, the deformation of the side frame 300 is restored, so that the front plate 310 and the rear plate 330 are clamped to the edges of the display panel 100 and the backlight module 200.

[0064] See also Figure 4 , the adhesive member 400 is an elastic colloid. The elastic colloid is a buffer glue 420. The buffer glue 420 can form a gap between the side panel 320 and the side of the display panel 100, and can also elastically protect the side glass, improve the impact resistance of the display panel 100, and also prevent the side frame 300 from poking the first protective film 140. Among them, the material of the buffer glue 420 includes but is not limited to at least one of UV glue, hot melt glue, epoxy glue, etc. Optionally, when the adhesive member 400 is an elastic colloid and is arranged on the side panel 320, it can be in a semi-cured state. During the process of installing the side panel 320 on the display panel 100 and the backlight module 200, the elastic colloid is slightly compressed by squeezing the elastic colloid, so that the elastic colloid is bonded to the side of the side panel 320 and the display panel 100. That is, the bottom of the elastic colloid is fixedly connected to the side of the side panel 320 facing the side, and the top of the elastic colloid abuts against the side of the display panel 100.

[0065] Optional, see Figure 5 The area between the side plate 320 and the side of the display panel 100 and the backlight module 200 except the adhesive 400 includes a gap 600 to be filled. Further, the area between the side plate 320 and the side of the display panel 100 and the backlight module 200 except the adhesive 400 is a gap 600 to be filled.

[0066] See also Figure 5 The display device 1000 further includes a filling glue 500. The filling glue 500 is disposed in all or part of the gap 600 to be filled. The filling glue 500 is disposed in the gap 600 to be filled in a manner including but not limited to a glue coating method before the side frame 300 is installed and a glue dispensing / injection method after the side frame 300 is installed.

[0067] Optional, see Figure 5 The adhesive 400 is a foam glue 410, one side of the foam glue 410 is bonded to the side panel 320, and a paste glue is applied to other positions of the side panel 320 of the side frame 300 where the foam glue 410 is not provided, and the side frame 300 is installed on the edge of the display panel 100 and the backlight module 200, and the foam glue 410 is squeezed to make the foam glue 410 bonded to the side of the display panel 100, and the filling glue 500 fills the gap 600 to be filled. The filling glue 500 can be cured by heating or air drying, and the cured filling glue 500 can fix and connect the front panel 310, the side panel 320, the bottom plate, the side of the display panel 100, and the side of the backlight module 200 together.

[0068] Optional, see Figure 6 , the adhesive 400 is a buffer glue 420, and the semi-cured or cured buffer glue 420 is set on the side plate 320, and the paste glue is applied to other positions of the side plate 320 of the side frame 300 where the buffer glue 420 is not set, and the side frame 300 is installed on the edge of the display panel 100 and the backlight module 200, and the buffer glue 420 is squeezed to make the buffer glue 420 adhere to the side of the display panel 100, and the filling glue 500 fills the gap 600 to be filled. The filling glue 500 can be heated and cured or air-dried and cured. After curing, the filling glue 500 can fix the front plate 310, the side plate 320, the bottom plate, the side of the display panel 100, and the side of the backlight module 200 together and maintain a small gap between the side plate 320 and the side of the display panel 100.

[0069] Optional, see Figure 7 and Figure 8 , the adhesive 400 divides the gap 600 to be filled into a first gap 610 and a second gap 620. The first gap 610 is located between the adhesive 400 and the side of the front plate 310 and the display panel 100. The second gap 620 is located between the adhesive 400 and the rear plate 330. At least part of the filling glue 500 is disposed in the first gap 610, and at least part of the filling glue 500 is disposed in the second gap 620. In other words, a portion of the filling glue 500 is fixedly bonded between the front plate 310, the side plate 320, the upper side of the adhesive 400 and the side of the display panel 100, and another portion of the filling glue 500 is fixedly bonded between the rear plate 330, the side plate 320, the lower side of the adhesive 400 and the side of the backlight module 200. This can increase the bonding area between the side frame 300 and the display panel 100, the backlight module 200, improve the bonding stability, and reduce the gap inside the side frame 300.

[0070] Optional, see Figures 9 to 11, the adhesive 400 has a plurality of conductive gaps 630. The conductive gaps 630 are connected to the first gap 610 and the second gap 620. At least part of the filling glue 500 is disposed in the conductive gaps 630. If the adhesive 400 is disposed along the extension direction of the side plate 320, and the adhesive 400 is also bonded between the side plate 320 and the side surface of the display panel 100, there may be a situation where the gaps on the upper and lower sides of the adhesive 400 are not conductive, thereby making it impossible for the filling glue 500 to fully move in the gap 600 to be filled (for example, it cannot move from the first gap 610 to the second gap 620), resulting in the inability to fill the gap 600 to be filled.

[0071] In the present embodiment, a plurality of conductive gaps 630 are provided to connect the first gap 610 and the second gap 620. Thus, even when the adhesive 400 is bonded to the side of the side plate 320 and the side of the display panel 100, the gaps on the upper and lower sides of the adhesive 400 are kept conductive. The filling glue 500 can fully move in the gap 600 to be filled (for example, it can move from the first gap 610 through the conductive gap 630 to the second gap 620), thereby enabling the filling glue 500 to fill the gap 600 to be filled.

[0072] Optional, see Fig. 9 , the number of the adhesive member 400 is one. The plurality of conductive gaps 630 all penetrate the adhesive member 400. For example, the adhesive member 400 is a strip of foam adhesive 410, the strip of foam adhesive 410 is arranged along the side plate 320, and the plurality of conductive gaps 630 penetrate the upper and lower sides of the strip of foam adhesive 410, so that the first gap 610 and the second gap 620 on the upper and lower sides of the strip of foam adhesive 410 are connected. During the process of applying the paste glue or dispensing glue at other positions of the side plate 320 of the side frame 300 where the foam glue 410 is not set, the filling glue 500 can be filled in the first gap 610, the conductive gap 630 and the second gap 620 under the extrusion force, and then fill the entire gap 600 to be filled, so as to improve the connection strength between the side frame 300 and the display panel 100 and the backlight module 200. By setting the filling glue 500 on the peripheral side of the display panel 100, the filling glue 500 can absorb external impact force and improve the impact resistance of the display device 1000.

[0073] Optional, see Fig.10, the number of the adhesive member 400 is one. The adhesive member 400 has a plurality of recessed portions at one end facing the side of the display panel 100. The recessed portions form the conductive gap 630. For example, the adhesive member 400 is a strip-shaped buffer glue 420, and the strip-shaped buffer glue 420 is arranged along the side plate 320. The strip-shaped buffer glue 420 has a plurality of recessed portions at one end facing the side of the display panel 100. A convex portion is formed between adjacent recessed portions. When one end of the strip-shaped buffer glue 420 facing the side of the display panel 100 abuts against the side of the display panel 100, each recessed portion forms a conductive gap 630, so that the first gap 610 and the second gap 620 on the upper and lower sides of the strip-shaped buffer glue 420 are connected. During the process of applying the paste glue or dispensing glue at other positions of the side plate 320 of the side frame 300 where the strip-shaped buffer glue 420 is not set, the filling glue 500 can be filled in the first gap 610, the conductive gap 630 and the second gap 620 under the extrusion force, and then fill the entire gap 600 to be filled, so as to improve the connection strength between the side frame 300 and the display panel 100 and the backlight module 200. By setting the filling glue 500 on the peripheral side of the display panel 100, the filling glue 500 can absorb external impact force and improve the impact resistance of the display device 1000.

[0074] Hot melt adhesive is coated on the side frame 300 , and the side frame 300 , the backlight module 200 and the display panel 100 are stably fixed together through the bonding effect of the hot melt adhesive, which is conducive to achieving the narrow frame requirement and improving the firmness of the display device 1000 .

[0075] Optional, see Fig.11 , the number of the adhesive members 400 is multiple. The multiple adhesive members 400 are arranged along the extension direction of the side plate 320. The gap between two adjacent adhesive members 400 is the conductive gap 630. For example, the adhesive member 400 is a foam adhesive 410, and the multiple foam adhesives 410 are arranged along the extension direction of the side plate 320. The gap between two adjacent foam adhesives 410 is the conductive gap 630. The first gap 610 and the second gap 620 on the upper and lower sides of the foam adhesive 410 are connected. During the process of applying the paste glue or dispensing glue at other positions of the side plate 320 of the side frame 300 where the foam glue 410 is not set, the filling glue 500 can be filled in the first gap 610, the conductive gap 630 and the second gap 620 under the extrusion force, and then fill the entire gap 600 to be filled, so as to improve the connection strength between the side frame 300 and the display panel 100 and the backlight module 200. By setting the filling glue 500 on the peripheral side of the display panel 100, the filling glue 500 can absorb external impact force and improve the impact resistance of the display device 1000.

[0076] Optional, see Fig.12 and Fig.13The side frame 300 has at least one opening 700. The opening 700 is connected to the gap to be filled 600. The opening 700 is used to fill the gap to be filled 600 with glue. The opening 700 is provided on the side plate 320 or the rear plate 330.

[0077] Specifically, after the side frame 300 is installed on the display panel 100 and the backlight module 200, glue can be filled into the gap 600 to be filled through the opening 700 to fill the gap 600. After the filling glue is cured into the filling glue 500, the fixing strength between the display panel 100, the backlight module 200 and the side frame 300 is improved. By arranging the filling glue 500 on the peripheral side of the display panel 100, the filling glue 500 can absorb external impact force and improve the impact resistance of the display device 1000.

[0078] Optional, see Figure 1 , the display device 1000 further includes a sealant 800 .

[0079] See also Fig.14 The backlight module 200 includes a back plate 210 and an optical component 220. The middle part of the back plate 210 is concave to form a receiving space. The optical component 220 is received in the receiving space. The edges of the back plate 210 are fixedly connected to the back of the display panel 100 through the sealant 800. Optionally, the sealant 800 also has a light shielding effect to prevent light from the optical component 220 from leaking out. The sealant 800 includes but is not limited to a light shielding double-sided tape, a light shielding foam layer, etc.

[0080] Furthermore, the sealant 800 can also prevent the filling glue from entering into the accommodating space.

[0081] See also Fig.14 The optical component 220 includes but is not limited to a reflector 221, a light guide plate 222 and an optical film 223 which are sequentially arranged from the back plate 210 to the direction where the display panel 100 is located. Further, the optical film 223 includes but is not limited to a diffusion film 224, a first light enhancement film 225 and a second light enhancement film 226 which are sequentially arranged from the back plate 210 to the direction where the display panel 100 is located. The backlight module 200 also includes a backlight source 230. The light emitted by the backlight source 230 is reflected, scattered, diffused, etc. by the optical component 220 and then emitted to be provided to the display panel 100, so that the display panel 100 can realize the display function.

[0082] Optional, see Figure 1 , Fig.13 and Fig.15The rear plate 330 is provided with at least one protrusion 331 protruding toward the front plate 310. The backlight module 200 is provided with at least one groove 240 on a side away from the display panel 100. The protrusion 331 is buckled with the side wall of the groove 240. The rear plate 330 of the side frame 300 is snap-connected with the back plate 210 of the backlight module 200.

[0083] Optionally, the side frames 300 are respectively arranged on the upper side, left side and right side of the back plate 210. In other words, the upper side, left side and right side of the back plate 210 are respectively connected to the rear plate 330 by hooks. The side frames 300 on the upper side, left side and right side of the back plate 210 can be interconnected as a whole or independently arranged. Optionally, the side frames 300 are formed by injection molding, and the corners of the side frames 300 are closed. The back plate 210 is formed by a sheet metal part through a stamping process, so the corners of the back plate 210 have process notches. After the side frames 300 are clamped on the back plate 210, the side frames 300 can just cover the notches in the corners of the back plate 210 to prevent light leakage. Of course, in other embodiments, the back plate 210 can also be formed by injection molding.

[0084] A circuit board is disposed on the lower side of the back plate 210 , and the circuit board is electrically connected to the lower end of the TFT array substrate 120 through a chip-on-film.

[0085] The present application proposes a low-cost narrow-frame display device 1000, which uses a side frame 300 to fix and protect the display panel 100 and the backlight module 200. The side frame 300 starts from the top surface 101 of the display glass and is fixed on the back plate 210, forming a complete C-shaped protection for the side of the display panel 100. In the present application, the inner wall of the side frame 300 is attached with a buffer foam glue 410, an elastic buffer glue 420 or a glue injection method, which can replace the glass side glue sealing; the side gap between the side frame 300 and the display glass is reduced by the elastic assembly of the injection-molded side frame 300, thereby effectively reducing the width of the screen frame, and has a relatively low risk of peeling and edge broken screen.

[0086] At the same time, the present application adopts an injection molded plastic frame as the edging side frame 300, and the edging side frame 300 replaces the glass side sealing, and the side frame 300 and the back panel 210 of the backlight module 200 are fixed by snaps, so that the present application has a relatively low cost and controllable cost while having a narrow frame function.

[0087] The display panel 100 includes one of an upper protective film or an upper polarizing plate, and also includes upper and lower display panels 100 , and also includes one of a lower protective film, a lower polarizing plate or a lower protective foam.

[0088] The upper protective film or the upper polarizing plate is designed to be inwardly contracted at the narrow frame, and the inward contraction width is ≥1mm, so as to form a fitting area that is close to the top plate. The material of the injection-molded side frame 300 includes but is not limited to conventional plastic materials such as black or gray PP, PC, PET, or a mixture thereof. The adhesive 400 includes a foam glue 410, which plays a buffering and fixing role; the sealant 800 is a double-sided adhesive or a double-sided foam glue 410; the back plate 210 is made of metal, and the metal back plate 210 needs to be punched at the position corresponding to the side frame 300 to form a groove 240 to facilitate the assembly of the side frame 300.

[0089] During the assembly process, the display panel 100 and the back plate 210 are first pre-fixed by means of the sealant 800; at the same time, the adhesive 400 is pre-fixed on the side frame 300, and the position of the adhesive 400 corresponds to the side of the display panel 100, which can provide side support and protection for the side of the display panel 100. Finally, the pre-assembled injection-molded side frame 300 is assembled with the pre-assembled display panel 100 and the back plate 210 to form a complete display device 1000; the injection-molded side frame 300 starts from the indentation of the upper surface of the display glass and is fixed on the back plate 210, forming a complete C-shaped protection for the side of the display panel 100.

[0090] The display device 1000 provided in this embodiment uses an adhesive 400 to replace the side sealant of a conventional display glass. Since the injection-molded side frame 300 and the adhesive 400 (e.g., foam) themselves have a certain deformation ability, the gap between the adhesive 400 (e.g., foam) and the display panel 100 is squeezed to achieve a 0 mm gap assembly, which reduces the width of the frame of the display device 1000 and also provides better protection for the sides of the product. In addition, the material cost is low and the assembly process is simple.

[0091] The adhesive 400 may be a buffer glue 420, and the buffer glue 420 includes but is not limited to black or gray UV glue, hot melt glue, epoxy glue and other materials. The adhesive 400 is injection molded when pre-assembled with the side frame 300, and needs to undergo corresponding curing treatment; and the side frame 300 is provided with an opening 700 on the side panel 320 or the back panel 330. When the side frame 300 after the injection of glue is assembled to the display panel 100 and the backlight module 200, a glue dispensing process may be performed at the opening 700 to further strengthen the connection between the side frame 300 and the display device 1000, and prevent the risk of peeling off and edge broken screen. In particular, the color of the filling glue 500 may be close to that of the side frame 300 to prevent poor appearance.

[0092] Furthermore, a decorative strip or a rubber strip of the same color as the side frame 300 may be attached to the area where the opening 700 is provided, so as to avoid the problem of poor appearance.

[0093] This embodiment uses a buffer glue 420 to replace the side glue seal of the conventional display glass; because the injection molded side frame 300 and the adhesive 400 (such as foam) themselves have a certain deformation ability, the gap between the adhesive 400 (such as foam) and the display panel 100 is squeezed, and the 0mm gap assembly reduces the width of the frame of the display device 1000, and also makes the side of the product have a better protection effect, and the material cost is low and the assembly process is simple. This embodiment also performs secondary glue fixation, which has a better fixing effect, and the risk of the display panel 100 falling off and the edge screen breaking is lower, and it still has a good cost advantage.

[0094] The above are some implementation methods of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
